my understanding is that radio telemetry doesn't have the same draw backs as optical telescopes. So having a space based radio dish is probably not necessary.

Telemetry by radar is quite different from ‘listening’, because you get to choose the frequency of the pulses. If we want to observe at wavelengths to which the atmosphere is opaque, we’ll have to do it from space. Present technology is incapable of putting an Arecibo-sized dish into orbit, but an array of small instruments might be feasible.

Perhaps putting an arecibo size dish to listen for ET signals, can it be done on the moon istead; or small listening dishes that piggyback on on other setalites. Imagine if the Voyager probes had a small radio signal listening dish. Just an idea

this was discussed thoroughly a year or so ago. the cost per launch vehicle(s) is so astronomically high the project would cost more to put it on the far side of the moon, build it and then have some means of transmitting the data back to earth. this is very unlikely to ever happenIn a rich man's house there is no place to spit but his face.

Back to the original question " wow signal planetary origin " seems to indicate it came from the vacinity of Tau Sagittarii in Saggitarius. It is a spectral type K1 or K2 giant, 1.5 - 2 Solar masses, with an apparent magnitude of +3.32. It is slightly cooler than our sun, of a light orange color.

because of the signal strength and the distance its highly unlikely to be from anything other than an earthly or natural source.In a rich man's house there is no place to spit but his face.

The frequency of the Wow! signal matches very closely with the hydrogen line, which is at 1420.40575177 MHz. Not sure what natural phenomena would cause that frenquency, so the question is, why so then SETI uses such frequency for search of non-terrestial readio signals? The location of the signal is in the constellation Sagittarius, with proximity to the Chi Sagittarii star group, and the visible star in that group is Tau Sagitarri.

The narrow bandwidth and non-persistence of the signal do not suggest a natural source of radio waves. The fact that the duration of the signal exactly matched that of a source moving with the fixed stars, through the beam of the radio telescope, strongly implies a distant origin, not one on or near Earth.

The Wow signal, will be to date the most mysterious radio signal captured, perhaps for brief a moment the Big Ear did capture a possible alien radio signal. To me sounds one random signal that the Big Ear caught, it was not a purposeful signal sent to Earth but one by ramdon chance; that implies why the signal was never heard again. As the computer data of the Wow sigal being analyzed by today's computers?

Apparently there was no intelligence or modulation in the signal. If it were alien then it must have been a beam or a beacon. The reason i say this is that it was not ever seen again when the telescope returned to that sky sector--therefore it was not spurious radiation from an alien radar .

Now, ask yourself if we were to send a "we are here" message wouldn't we want to make it unambiguous that it was sent by sentient beings.

I conclude that the WOW signal was a glitch in the equipment: either the electronics, power supply, antenna or the receiver.

If an alien radio receiver was by chance poiting towards one the Voyager probes, and that alien radio telescope captured its radio signal and determining it was artificial in nature. Such a scnario implies random chance artificial radio signal. Just too intringing that The frequency of the Wow! signal matches very closely with the hydrogen line, which is at 1420.40575177 MHz. Thus the possibility remains that it could have been non terrastial, but also could have been an equipment glitch or military communications. The possability remains still that the WOW signal could have been the real thing. That is why there is SETI, Kepler and other probes looking for life in the cosmos.

voyager wasn't equipped to detect let alone transmit radio data from that distance. they are on basic life support now. they are checked in on every so often but there is no real science being actively conducted on the missions now. As I recall they did send back radio transmissions of the planets. It was never intended to search deep space for signalsIn a rich man's house there is no place to spit but his face.

i used voyager probe as an example, one could say, any orbiters that orbit the sun, or mercury, titan, so a powerful alien antena is capable of detecting signals from those probes. Might be those signals be radio signals, or diferent emissions from the spectrum, x ray, infrared,

Phew! Where have you been scientifically?!

Both Voyagers are very actively mapping out the heliosphere. They're even doing commanded pirouettes at regular intervals to 'take a look around'.

They might be very old and many light-hours away, but they're still researching for us all...

well yes they are looking around though they aren't looking for ET. their job is to tell us what its like beyond the heliosphere. In a rich man's house there is no place to spit but his face.

Do the Voyager probes have radio signals? how does NASA communicate with them, through radio signal, imagine now an alien antena doing the same thing, they the furthest artificial objects from Earth, it would not be out of this world if a powerful alien radio receiver captured the probe's radio signals.

yes they send a signal back and a bit of telemetry. They are reaching the end of their power capacity. The radioactive material the probes use for heat and energy are fading. IIRC the probes send a very low watt signal towards us. If you google search it I'm sure you could find what the frequency is so you could hear it as well. You'd probably need to know exactly which direction to point your receiver to actual hear itIn a rich man's house there is no place to spit but his face.

With that said, I can't find any conclusive evidence that the actual signal was ever transcribed (if it could be in the first place) to audio. Any thoughts?

It probably could have been. After all radio signals are a for of audio as far as I know."By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible". Hebrews 11.3
